3rd Clutch
The 3rd clutch engages/disengages 3rd gear, and is located at the end of the countershaft, opposite the end cover. The 3rd
clutch is supplied hydraulic pressure by its ATF feed pipe within the countershaft.
ilth Clutch
The 4th clutch engages/disengages 4th gear, as well as reverse gear, and is located at the middle of the mainshaft. The 4th
clutch is joined back-to-back to the 2nd clutch. The 4th clutch is supplied hydraulic pressure by its ATF feed pipe within the
mainshaft.
One-way Clutch
The one-way clutch is positioned between the park gear and the countershaft 1st gear, with the park gear splined to the counter-
shaft. The countershaft 1st gear provides the outer race surface, and the park gear provides the inner race surface The
one,way clutch locks up when power is transmitted from the mainshaft lst gear to the countershaft 1st gear. The 1st
clutch and gears remain engaged in the 1st, 2nd, 3rd, and 4th gear ranges in the lo], pt, E, or E position The one-way
clutch disengages when the 2nd, 3rd, or 4th clutches/gears are applied in the lor, [d, E, or E position'
This is because the increased rotational speed of the gears on the countershaft over-ride the locking "speed range" of the
one-wav clutch. The one-wav clutch free-wheels when the lst clutch is engaged

Ascending Control {37 Modol}
When the PCM determines that the vehicle is climbing a hill in E] and E positions, the system extends the engagement
area of 2nd g€ar and 3rd gear to prevent the transmission from frequently shifting between 2nd and 3rd gears, and
between 3rd and 4th gears, so the vehicle can run smooth and have more power when needed.
NOTE:
. Shift schedules stored in ths PCM between 2nd and 3rd gears, and between 3rd and 4th gears. enable the PCM's fuzzy
logic to automatically select the most suitable gear according to the magnitude of 8 gradient.
t Fuzzy logic is a form of artificial intslligence that lets computers respond to changing conditions much like a human
mind would.

Apply power steering fluid to the surface of the spe-
cial tool. Set the new seal rings over the special tool
from the smaller diameter end of the tool. and
expand the seal rings. Install two rings at a time
Jrom each end ofthe sleeve.
Note these items when installing the seal ring:
. Do not over-expand the seal ring. Install the resin
seal rings with care so as not to damage them.
After installation, be sure to contract the seal
rings using the specialtool {sizing tool).
. There are two types of sleeve seal rings: black
and brown. Do not mix the different types of
sleeve seal rings as they are not compatible.
Align the special tool with each groove in the sleeve,
and slide a sleeve seal ring into each groove. After
installation, compress the seal rings with your fin-
gers temporarily.

Shim selection:
Set the four 32 mm shims on the bearing surface of the
gearbox housing. Total thickness of the four shims
should equal no more than 0.70 mm.
Shim set: four 32 mm shims (Thickness: 0.10 mm, 0.15

Knuckle/Hub Replacement
Note these items during replacement:
. Replace the selt-locking nuts after removal.
. The vehicle should be on the ground before any bolts or nuts connected to rubber mounts or bushings are tightened.
. Torque the castle nuts to the lower torque specifications, then tighten them only far enough to align the slots with each
pin hole. Do not align the nuts by loosening.
o Use only genuine Honda wheel weights for aluminum wheels. Non'genuine wheel weights may corrode and damage
the aluminum wheels.
. Onthealuminum wheels, remove the center cap from the inside of the wheel after removing the wheel.
. Before installing the brake disc, clean the mating surfaces of the front hub and brake disc.
. Before installing the wheel. clean the mating surfaces ofthe brake disc and wheel.
. Wipe off the grease before tightening the nuts at the balljoints.
